Please read carefully before installing
Product is tested to and recognized to UL 2703 standards for safety grounding and bonding
equipment and meets UL 1703 fire standards.
SunModo PV Rack Mount System can be used to mount photovoltaic (PV) panels in a wide
variety of locations. All installations shall be in accordance with NEC requirements in the USA.
The self-bonding system is for use with PV modules that have a maximum series fuse rating of
30A. Mechanical design loads per UL 2703: Downward Pressure: 33.42 psf (1600.2 Pa),
Upward Pressure: 22.28 psf (1066.8 Pa), Down-Slope: 5 psf (239.4 Pa).

Installer Responsibility:
Before ordering and installing materials, all system layout dimensions should be confirmed by field
measurements. SunModo reserves the right to alter, without notice, any details, proposals or plans. Any
inquiries that you may have concerning installation of the PV system should be directed to your SunModo Sales
representative. Consult SunModo Sales for any information not contained in this manual. This manual is
intended to be used as a guide when installing SunModo’s EZ Standing Seam Clamps on pitched roofs. It is
the responsibility of the installer to ensure the safe installation of this product as outline herein.
Installer shall employ only SunModo products detail herein. The use of non SunModo
components can void the warranty and cancel the letters of UL compliance.
Installer shall guarantee that screws and anchors have adequate pullout strength and shear
capacities.
Installer shall adhere to the torque values specified in this Instruction Manual.
Installer shall use anti-seize compound, such as Permatex anti-seize, lubricant is recommended
for all threaded parts.
Installer is responsible to install EZ Standing Seam Clamps over a Fire Resistant roof covering
rated for the application.
Installer is responsible to determine that the roof, its rafters, connections, and other architectural
support components can sustain the array under all code level loading conditions.
Installer shall adhere to all relevant local or national building codes. This takes account of those
that supplant this document’s requirements.
Installer shall guarantee the safe placement of all electrical details of the PV array.
Installer shall comply with all applicable local, state and national building codes, including
periodic re-inspection of the installation for loose components, loose fasteners and any
corrosion, such that if found, the affected components are to be immediately replaced.
Installer to ensure the structural support members or footings for mounting the array can
withstand all code loading conditions. Consult with licensed professional engineer for the
appropriate loading conditions.
Installer to follow all regional safety requirements during installation.
This racking system may be used to ground and/or mount a PV module complying with UL 1703
only when the specific module has been evaluated for grounding and/or mounting in compliance
with the included instructions.
Safety:
Review relevant OSHA and other safety standards before following these instructions. The installation of solar
PV systems is a dangerous procedure and should be supervised by trained and experienced personnel.
It is not possible for SunModo to be aware of all the possible job site situations that could cause an unsafe
condition to exist. The installer of the roof system is responsible for reading these instructions and determining
the safest way to install the roof system. These instructions are provided only as a guide to show a
knowledgeable, trained erector the correct part placement one to another. If following any of the installation
steps would endanger a worker, the erector should stop work and decide upon a corrective action. Provide
required safety railing, netting, or safety lines for crew members working on the roof.

SunModo Self-Grounding System
SunModo developed a proprietary grounding and bonding system that is built into the mounting
hardware for the rails, clamps and splices. We provide further grounding through all of the SunBeam
racking components including the Pipe Caps, Beams, Posts and Post Base Plates. All hardware meet
UL 2703 Grounding and Fire Standards tested by ETL.
The basis of the system is our patented stainless steel floating grounding pin which is designed to be
captive in the mounting components and provides a bonding path from the PV panel frames to the rails
and rail splices, and finally to the ground lug. The self-grounding and bonding system is for use with PV
modules that have a maximum series fuse rating of 30A. The maximum number of PV modules is
limited by the system voltage, so in a system has multiple inverters, the SunModo racking system can
theoretically go on forever.
Finally we have added a spring and Blue 242 Loctite to our Mid Clamp assemblies. The sprig keeps the
Mid Clamp in the open position ready to receive the solar module. The Blue Loctite is a light bonding
agent allowing the T-Bolt engagement into the Rail when the Collar Nut is turned from above. The Blue
Loctite has the added benefit of being an anti-seize agent for stainless steel hardware in the area where
it is applied. For additional anti-seize protection refer to the Tools Required for Installation’ section of
this document.
Mid Clamp with Ground Pins
Similarly, the rail splices the grounding pins, eliminating the need for extra bonding components.

Portrait Panel Configuration:
With a full range of components the EZ Standing Seam Roof Mounting System can be
configured in an endless variety of designs.
A typical portrait roof layout features two East-West rails mounted to North-South seams
using the EZ Standing Seam Roof Mounting System. Mid Clamps are used between PV
panels, they will produce 1/2” spacing between PV panel frames. End Clamps are used to
secure PV panels at the ends of a row.
The EZ Standing Seam Roof Mounting
System can be mounted in a staggered
fashion so that the loads are shared across
the seams. Consult a structural engineer for
attachment frequency and roof construction.

EZ Standing Seam Roof Mounting System Installation:
1. Select the correct EZ Standing Seam Roof Mounting System to fit your roof. Snap a line or use
a laser to line up the clamps on the roof panel seams.
2. Tighten to the torque value appropriate for your roof panel material. Tighten to 10 ft. lbs. of
torque for steel panels and 8 ft. lbs. of torque for aluminum panels.
3. Install the L-Foot to the Standing Seam Clamp in the desired orientation. Then attached the
HR Series Rail to the L-Foot.

Landscape Panel Configuration:
The EZ Standing Seam Roof Mounting System conveniently accommodates landscape
configurations to minimize roof time and parts required. Our Shared Rail Adaptors End Clamps and
Mid Clamps kit converts standard HR Rail to shared rail to allow landscape mounting of PV panels
on E-W rails. Because the rails are shared, a two-up installation would require only three rails as
compared to four for a standard mid and end clamp system.
These pre-assembled Mid Clamps have a unique T-Bolt locking feature
that ensure the T-Bolt remains vertical and in full contact with the rail to
eliminate pull out. The spring-loaded top clamp and open collar nut
accommodates module frames from 31 to 50 mm. The added Loctite
easily engages the T-Bolt from the top of the collar nut. The shared rail
adaptor converts standard rail to shared rail to allow landscape mounting
of PV panels on E-W rails.
The SunModo self-grounding system that
includes the pre-assembled universal bonding clamp eliminates separate
module grounding hardware and saves installation cost.
